[casr-afl] [LSAN] not correct CrashSeverity

[WhiteWLf-dev]

LSAN.zip

Dear Colleagues.

I encountered an issue in casr-afl and would like to report it. CrashSeverity should be allocation-size-too-big, but it is memory-leaks.

Steps to reproduce

git clone https://github.com/lua/lua.git
sudo apt install libreadline8
cd lua
git checkout v5.4
export AFL_USE_LSAN=1
CC="afl-clang-fast -Wno-everything" make -e
unzip LSAN.zip #take it from the attachments
casr-afl -i LSAN -o report -- ./lua
cat report/id:000000,sig:00,src:000338,time:1244084,execs:127213,op:havoc,rep:1.casrep

Expected Behaviour

CrashSeverity field is allocation-size-too-big.

Actual Behaviour

CrashSeverity field is memory-leaks.
